About Crypto Address Checker
A checker for crypto addresses that reads the characters and nothing else.
What it does
It recognises the network and address type from the string, splits the address into prefix, payload and checksum, verifies the checksum where the format has one, and lists what to watch out for before sending. Every rule comes from the format's specification (BIP-173, BIP-350, EIP-55, the CashAddr specification, XLS-5d, SEP-23, CIP-19 and others) and is tested against the vectors those specifications publish.
What it deliberately does not do
- It does not send the address anywhere. The checker pages are not allowed to open any network connection.
- It does not look up balances, transaction history, owners, names or scam lists — each of those needs a request carrying the address.
- It never asks for a private key, recovery phrase or view key, and has no key generator.
- It never says an address belongs to the right person. A valid format only means the address is well-formed.
